Pierburg CWA100-3

The CWA100-3 is a successor of the CWA100-2 we are also offering. The dimensions and the weight is nearly the same.
New is the freshly designed impeller housing with slightly shorter water in and outlets and the bigger electrical connector.
This improves the handling of bigger cable diameters significantly.
Suitable for instance for intercooling in combustion engine vehicles and cooling of various systems in electrical vehicles.

Know-how:

* Pump pressure is not the same as the system pressure.
Those pumps can of course be used in normal automotive cooling systems with system pressures
in the range of 0.8 to 1.2 bar for instance.
The pump pressure or differential pressure expresses the ´resistance´ of which the pump has to work against.
Tip: A mechanical thermostat is responsible for about half of that resistance. (in most cars)

 

Controller:

We will gladly provide you with our controller (tinyCWA) to control the pump.
Just write us an email in this matter or take a look here at our online store. :-)
